Calculate the potential growth and tax benefits of a Cash Rollover Unit Trust (CRUT).
Understanding the CRUT Calculator
A Charitable Remainder Unit Trust (CRUT) is a type of split-interest charitable giving vehicle that allows an individual to transfer assets to a trust and receive an income stream for life or a specified period. At the end of the term, the remaining assets in the trust are distributed to one or more designated charities. This calculator helps you estimate the potential financial outcomes of establishing a CRUT.
The primary goal of a CRUT is to provide a future benefit to a charity while offering the donor an income stream and potential tax advantages. Understanding how contributions, growth, and withdrawals interact is key to appreciating its value.
How the CRUT Calculator Works
This calculator simplifies the complex calculations involved in CRUT projections. It takes into account several key factors:
Initial Investment Amount: The principal sum or assets transferred into the trust at its inception.
Annual Contributions: Any additional funds or assets contributed to the trust each year.
Assumed Annual Investment Growth Rate: The projected average annual return on the trust's assets. This is a critical assumption and actual returns may vary significantly.
Tax Deferral Period (Years): The duration for which the trust's earnings can grow tax-deferred before being distributed. For many CRUTs, this is the lifetime of the income beneficiary(ies).
Annual Withdrawal Rate for Income: The percentage of the trust's value that is withdrawn annually to provide an income to the beneficiary. This rate is typically fixed as a percentage of the trust's value, revalued each year.
The Underlying Mathematics (Simplified)
The calculation is an iterative process that simulates the trust's performance year by year. For each year, the following steps are generally performed:
Add Contributions: If there are annual contributions, they are added to the trust's current value at the beginning of the year.
Value_after_contributions = Current_Value + Annual_Contributions
Apply Investment Growth: The assets grow based on the assumed annual growth rate.
Value_after_growth = Value_after_contributions * (1 + Investment_Growth_Rate / 100)
Calculate Withdrawal: The income withdrawal is calculated based on the current value of the trust and the annual withdrawal rate.
Withdrawal_Amount = Value_after_growth * (Annual_Withdrawal_Rate / 100)
Determine End-of-Year Value: The withdrawal is subtracted from the value after growth to get the value at the end of the year.
End_of_Year_Value = Value_after_growth - Withdrawal_Amount
This process repeats for the specified number of years (or the lifetime of the beneficiary). The calculator aggregates the total income received by the beneficiary and estimates the final value of the trust that would eventually pass to the charity.
Use Cases and Benefits
CRUTs are versatile financial tools used for various purposes:
Retirement Income: Providing a supplemental income stream during retirement.
Charitable Legacy: Supporting favorite charities with a significant future gift.
Tax Planning: Deferring capital gains taxes on appreciated assets and potentially receiving an upfront income tax deduction for the charitable portion.
Estate Planning: Reducing estate tax liability by transferring assets to a trust.
Asset Diversification: Allowing donors to move from concentrated or illiquid assets into a diversified portfolio managed within the trust.
